Vehicle-mounted movable full-automatic coal sampling and sample preparation machine and coal sampling method thereof

Abstract

The invention provides a vehicle-mounted movable full-automatic coal sampling and sample preparation machine and a coal sampling method of the vehicle-mounted movable full-automatic coal sampling and sample preparation machine. The sampling and sample preparation machine comprises an automobile chassis (1), an auxiliary frame, hydraulic supporting legs (4 and 8), a sampling device (7), a sample preparation device (3), a sample collecting device, a sample discarding box (2), a hydraulic oil tank (5), a cooler (6) and an electric control cabinet (9), wherein the auxiliary frame is arranged on the automobile chassis (1); and other parts are arranged on the auxiliary frame. The coal sampling and sample preparation machine integrates the functions of sampling, sample feeding, sample preparation, sample collecting and sample discarding, can provide an accurate and reliable sample for the coal quality analysis and test, and has the advantages of high working efficiency, wide application range, high degree of automation, safety and convenience in operation and the like.

Description

technical field [0001] The invention relates to the field of coal sampling and preparation, and more specifically relates to a vehicle-mounted movable fully automatic coal sampling, sample preparation, and sample collection intelligent integrated equipment and a coal sampling and preparation method thereof. Background technique [0002] Coal analysis is the basic work of coal quality monitoring and quality control. Only when the data of coal analysis is accurate can the coal quality be correctly evaluated and quality control implemented. The object of coal analysis is the collected coal samples. Therefore, how to collect efficiently is more important. Representative coals are of great importance for coal analysis. The current coal sampling is divided into manual sampling and fixed gantry sampling. The main working principle of the fixed gantry sampling is that after the automatic positioning of the compartment is realized by the ultrasonic induction device, the electric cont...

AI Technical Summary

Problems solved by technology

Manual sampling has the following disadvantages: 1), sampling is labor-intensive, and work efficiency is low; 2), sampling accuracy is low, and human factors are relatively high; 3), sampling safety protection measures are insufficient, and safety accidents are prone to occur

The traditional fixed gantry sampling also has the following disadvantages: 1) The fixed gantry sampling and preparation device is fixed and cannot be moved, and has poor flexibility. It cannot be flexibly moved to different work sites for sampling and sub-sampling, and the degree of automation and intelligence is low; 2. ), the fixed gantry-type sample collection and preparation device has a large investment cost, and it needs to build additional facilities such as corresponding foundations and steel structure skeletons, and the additional cost is huge. Therefore, it is urgent to develop a coal sampling and preparation machine with complete functions, flexibility and practicality, and a very high degree of automation
